For example, the vast majority of people with memory loss do not have problems with a loss of self-identify (meaning that they know exactly who they are). In addition, sudden head trauma (such as that which may occur in a car accident) may cause some confusion or disorientation, but it rarely leads to amnesia.
Stroma is the thick fluid within the chloroplast. I think you mean 'Stroma'. Stroma can refer to two things in Biology. Stroma is the fluid inside chloroplasts, the site of photosynthesis in all plant cells. It is also, however, the framework (like a skeleton) inside any biological tissue, cell or organ.
Stroma is everything else -- connective tissue, blood vessels, nerves, ducts. The parenchyma / stroma distinction provides a convenient way to circumvent the listing of tissue types when discussing an organ. Examples: 1  The parenchyma of the kidney is epithelial tissue (renal tubules and corpuscles).2  The blood vessels, nerves, and supporting connective tissue of the kidney comprise the stroma. 3  The parenchyma of the spleen is connective tissue (mostly lymphocytes and other blood cells).he parenchyma / stroma distinction provides a convenient way to circumvent the listing of tissue types when discussing an organ.
